TV Unit Height: How to Get It Right for Your Room

on

The right TV unit height is the one that puts the middle of your screen level with your eyes when you are seated. For most UK living rooms that means a unit between roughly 40 and 60 cm tall, lower for a bigger screen and higher for a smaller one. Below you will find the rule, a table that turns it into centimetres for 55, 65 and 75 inch TVs, and the clearance and safety checks that decide whether the unit actually works in your room.

TL;DR

  • Aim to have the vertical centre of the screen at your seated eye level, which for most adults is between 90 cm and 110 cm from the floor.
  • Bigger screens need lower units: a 75 inch TV usually sits on a shorter unit than a 55 inch one, because more of the screen sits above the unit.
  • Allow at least 10 cm of breathing space around the TV, and 10 to 15 cm between the screen and a soundbar.
  • Measure your own seated eye height from the sofa before you buy. Averages are a starting point, not an answer.
  • Anchor tall or top-heavy units to the wall and push the TV towards the back of the surface, especially if children visit.

The rule that decides TV unit height

Every guide that ranks for this question lands on the same principle. Philips says the ideal is to align the vertical centre of the screen with your seated eye level, and that most adults sitting in a relaxed posture have an eye level between 90 cm and 110 cm from the ground. Wirecutter puts it in terms of posture: the screen centre should be roughly level with your eyes in your usual viewing position, shoulders down, neck straight, chin neither tilted down nor jutting up.

Notice what this means. The unit is not the thing you are trying to get right. The screen centre is. The unit is simply the base that lifts the TV to the correct height, so its ideal height depends on three things: your eye level, the height of your TV, and the gap between the top of the unit and the bottom of the screen.

That is why a single “standard TV unit height” does not exist. A 55 inch screen and a 75 inch screen need different units to reach the same eye line.

Measure your seated eye height first

This takes two minutes and removes most of the guesswork.

  1. Sit on your sofa or chair in your normal viewing posture, not perched upright.
  2. Ask someone to measure from the floor to the level of your eyes. Or hold a pencil level with your eyes against the wall and measure that.
  3. Write the number down in centimetres. Anywhere from 90 to 110 cm is typical, but Ross’s UK guidance gives a seated eye height of 42 to 46 inches (107 to 117 cm) and stresses that it varies by person. Your sofa matters too: a deep, low sofa puts your eyes lower than a firm, upright one.
  4. If two people of different heights share the sofa, measure both and aim for a figure in between.

A low-slung sofa is the most common reason a “standard” unit feels too high. If you are also choosing a coffee table for the same sofa, the seat height matters there as well, and we cover it in our guide to coffee table height for UK sofas.

From eye level to unit height: a worked method

Once you know your eye level, the sum is short:

Unit height = seated eye level − half the screen height − the gap between the top of the unit and the screen’s bottom edge

The gap is the space taken by the TV’s feet or stand and the bezel. On many TVs it is around 5 cm, but check your own: measure from the underside of the feet to the bottom edge of the lit picture.

Half the screen height comes from the diagonal size. For a standard 16:9 TV, the screen height is about 49% of the diagonal. That gives roughly 68 cm for a 55 inch screen, 81 cm for a 65 inch and 93 cm for a 75 inch. Half of each is about 34 cm, 40 cm and 47 cm.

Here is the sum worked through, assuming a 5 cm gap:

TV size Screen height (approx.) Unit height if eye level is 90 cm If eye level is 100 cm If eye level is 110 cm
55 inch 68 cm 51 cm 61 cm 71 cm
65 inch 81 cm 44 cm 54 cm 64 cm
75 inch 93 cm 38 cm 48 cm 58 cm

These figures are our own arithmetic from the formula above, so treat them as a guide and swap in your own measurements. Two things stand out. First, the bigger the TV, the lower the unit. Second, a sofa with a lower seat pulls everything down, so a 75 inch screen can call for a unit under 40 cm tall.

If you want the 55 inch case in more detail, we have a dedicated guide on choosing a TV stand height for a 55 inch TV. For larger screens, see what to check before buying a 75 inch TV stand.

What if the maths gives a height you cannot find?

You will not always find a unit at exactly 48 or 61 cm, and you do not need to. Philips says that if the screen centre cannot sit exactly at eye level, the top edge should be no more than 15 cm above eye level, and a slight upward tilt of around 10 to 15 degrees is fine. So a unit a few centimetres lower is better than one a few centimetres too high. Looking up for a two-hour film is what causes neck ache, not looking slightly down.

Does viewing distance change the height?

It changes how big a screen suits the room, and that in turn changes the unit. LG UK recommends a viewing distance of 1.7 m for a 55 inch 4K TV. If your sofa is further back than that, a larger screen starts to make sense, and with it a lower unit.

Some guides add a distance term to the height calculation. KEF UK uses TVH = EL + (VD × 0.22), where EL is seated eye height and VD is viewing distance, both in inches. Its worked example for a 65 inch TV uses an eye height of 36 inches and a distance of 109 inches, giving a screen centre of about 60 inches (152 cm). That is a deliberate raise above eye level for a mounted screen, and it sits far higher than the seated-eye rule above. For a unit that sits on the floor in a normal living room, the simpler eye-level rule is the one to follow. A centre that high would put your neck at a poor angle on a sofa.

Typical TV unit heights, in centimetres and feet

When readers search for TV unit dimensions in feet, they usually want a sense of scale. One foot is 30.48 cm, so:

  • A low unit of 40 cm is about 1 ft 4 in.
  • A mid-height unit of 50 cm is about 1 ft 8 in.
  • A taller unit or sideboard of 60 cm is about 2 ft.
  • A unit of 75 cm is about 2 ft 6 in, which is closer to console or sideboard height than a classic TV stand.

In practice, most living room TV units sit in the 40 to 60 cm band. Taller sideboards used as TV bases are fine for smaller screens, or for tall sitters, but they push a big screen too high for a seated viewer. If you want a unit with storage, check that the height still works with your TV size. Our guide to choosing an oak TV stand covers how size, storage and fit trade off.

Width and depth matter as much as height

A unit at the perfect height can still be wrong. Philips advises choosing a stand at least as wide as the TV’s base, and making sure the TV sits securely. Check where the feet sit too: many modern TVs have feet set wide apart at the edges, so the unit has to be wider than the screen, not just the base.

We look at width and footprint in detail in our TV unit size guide for 55 and 65 inch TVs. And before you order, our checklist for measuring your living room media centre walks through wall width, depth and the clearance for doors and radiators.

Clearance: ventilation, soundbars and equipment

Height is not only about the unit. You need room around the screen as well.

  • Ventilation: Samsung UK says the TV’s top, bottom and sides should generally be at least 10 cm from other objects. A shelf directly above the screen in a tight alcove is the classic mistake.
  • Soundbar: Mount TV’s UK guidance recommends a 10 to 15 cm gap between the bottom of the TV and the top of the soundbar, and says 5 cm can work if the TV’s infrared sensor is not on the bottom edge. A soundbar in front of the screen raises the effective bottom edge, so subtract its height from your gap when you work out the unit height. If the soundbar sits on the unit, the unit can be slightly lower to compensate.
  • Set-top boxes and consoles: if you want them on the same surface, check shelf depth and the space between shelves. Closed cabinet doors trap heat, so choose a unit with open compartments or ventilated backs for anything that runs warm.

Some owners find the soundbar sits at a different height from where the sound should come from. One forum poster describes a conflict between placing a soundbar at ear level and the screen centre at eye level, and suggests raising and tilting the screen as one compromise. For most rooms, though, putting the soundbar directly below the screen is perfectly good.

Wall-mounted TV: how high is too high?

Mounting changes the question: now you are choosing a unit to sit beneath a screen, not under it. Homebuilding says a wall-mounted TV is generally best with its centre at seated eye level, approximately 42 to 50 inches (107 to 127 cm) from the floor, and warns that mounting above a fireplace can force an uncomfortable viewing angle. The Philips tolerance applies here too: keep the top edge within 15 cm above eye level.

If you have a wall-mounted screen, the unit beneath it becomes a low sideboard, and its height only has to clear the screen’s bottom edge, plus any soundbar, by a sensible gap. A lower unit with a wall-mounted TV gives you more freedom to choose a height for the screen itself. In a compact room, floating or wall-hung units can also free up floor area: we compare them in our guide to wall-mounted vs freestanding TV units.

Seating position matters sideways too

Centre the television relative to the main seating area, not simply the wall, especially in asymmetrical rooms, as one media wall planning guide suggests. If the sofa sits off-centre to a chimney breast or a window, the unit should follow the sofa for viewing comfort, with the rest of the wall styled around it.

Glare and light

A perfectly placed screen is still frustrating if a window reflects in it. Place the unit at right angles to the main window where you can, use curtains or blinds, and read this guide on how to reduce TV glare if you rent and cannot change the room much.

Safety checks before you place or mount

A TV is heavy and top-heavy, and tall furniture adds to the risk. Lancashire County Council cautions that unsecured furniture and televisions can tip over, especially when curious children climb on them, and recommends anchoring all heavy or unstable furniture to walls. Its safety suggestion for TV stands is to place the television towards the back of the stand to improve stability. If you have toddlers or grandchildren visiting, use the wall anchors as well as the placement tip, and keep remote controls and tempting items off the top.

If you mount the TV on the wall, Which? advises checking that the mount supports the TV’s size and weight, and using a stud finder to locate wooden studs in hollow walls, because the gaps between them are not strong enough to hold a TV. If you are not confident drilling into your wall, use a qualified installer.

One more note for motorised mounts: the HSE warned in 2025 that motorised height-adjustable display mounts in education settings can cause crushing injuries and should be fitted with anti-collision devices. That bulletin is about schools, but the sensible lesson at home is to install any motorised lift as the manufacturer instructs and keep fingers and children clear.

Our perspective

Our perspective — overview diagram

Most buyers ask us for a number, and the honest answer is that the number comes from their sofa, not from us. The mistake we see most is people picking a unit for how it looks in a photo, then finding that a 65 or 75 inch screen sits so high that the film is watched with the chin tilted up.

Our advice is to choose the unit last. Measure your seated eye height, decide on the screen size, run the sum in the table above, and only then look for a unit. Solid oak units are made to order, so height, finish and assembly options can be tailored to the figure you have worked out, which is far better than settling for a stock height that is five or ten centimetres off. For buyers over 40, and for small rooms where the TV is the focal point, comfort over a long evening matters more than anything else, and the unit should come ready for you to put in place without time spent on assembly.

Common mistakes to avoid

  • Buying the unit before the TV. Feet, bezel and soundbar all change the maths.
  • Ignoring the sofa. A low sofa drops your eye line by several centimetres.
  • Choosing a sideboard because it looks good. Taller sideboards suit smaller screens and tall viewers.
  • Pushing the TV flush into an alcove. Leave at least 10 cm for ventilation.
  • Leaving heavy units unanchored in homes with children.

FAQ

What is the best height for a 65 inch TV unit?

For most seated viewers it is around 44 to 64 cm, depending on your eye level, which is typically 90 to 110 cm. At an eye level of 100 cm and a 5 cm gap under the screen, the sum gives about 54 cm. Measure your own seated eye height to refine it.

Is a TV unit too high if I look up at the screen?

Yes, if you have to tilt your chin up regularly. Philips says the top of the screen should be no more than 15 cm above eye level, and that a slight tilt of 10 to 15 degrees is acceptable. Anything higher is better solved with a lower unit.

How much space should I leave around the TV?

At least 10 cm at the top, bottom and sides for ventilation, according to Samsung UK. If you add a soundbar, leave 10 to 15 cm between the bottom of the TV and the top of the soundbar, or 5 cm if the TV’s infrared sensor is not on the bottom edge.

Do I need to secure a TV unit to the wall?

It is a good idea for any tall or heavy unit, particularly where children are around. Lancashire County Council recommends anchoring heavy or unstable furniture and placing the TV towards the back of the stand. Use wall fixings suited to your wall type.
